We don't need to read the host's hostname through /mnt/root/etc/hostname,
because the hostname is written to config.json on a change. When the hostname
has never changed, it won't be found in config.json, so we can default to
the Supervisor container's /etc/hostname as it will match the host's
/etc/hostname, the network mode being `host`.

That way that this is performed is by first adding a depends_on entry
for the target service if it appears in a network mode. Then when we
generate the docker container for this service, we use the containerId
of the target container and replace the network_mode with
`container:<id>`.
When comparing state, we check that the containerId still points to the
contianerId of the target container, and in this way we ensure that
when a network mode target container changes, we change the dependent
container too.
